Resumo:   ABSTRACT: This article deals with the synthesis and formation of mesoporous titania films by latex beads templating. The infiltration of latex template by titanium precursor solution resulted in compact films that generated an inverted pore network resulting from the latex removal as it was observed by Scanning Electron Microscopy (SEM) measurements. The goal of this work is to analyze the deposition of latex beads on glassy substrates and eventual infiltration by precursor solution of mesoporous titania. The final product was bulky films with porosity in the micrometric scale defined by latex beads. The synthesis of latex beads was carried out in the absence of N2 and the titania precursor solution was obtained from the ternary system: HCl/P-123/1 Butanol. The characterization of films by SEM was carried out after the removal of latex template by calcination in a tubular oven. The appearance of films was compact for 30% V/Vo  dispersion concentration and there was a well-defined pore network observed in the SEM characterization associated with the presence of latex beads that assembles by Solvent Controlled Evaporation (SCE) technique. SEM characterization showed that latex beads coated on glass substrates and formed a network structure that could be applied to functional devices like solar cells, catalizers and batteries.  It is necessary to decrease the concentration of the dispersion to form films with homogeneous monolayers that become transparent to visible light. KEYWORDS: Nanotechnology, semiconductor oxide, self-structured materials.

A infiltração do molde por solução precursora de titânia resultou em filmes compactos que geraram uma rede de poros invertida decorrente da remoção do molde como foi observado por medidas de Microscopia Eletrônica de Varredura (MEV). O objetivo deste  trabalho consiste em analisar a deposição de esferas de látex em substratos de vidro e eventual infiltração por solução precursora de titânia mesoporosa. O produto final foi filmes compactos com porosidade na escala micrométrica definida pelas esferas de látex. A síntese das esferas de látex realizou-se na ausência de N2 e a solução precursora de titânia foi obtida a partir do sistema ternário: HCl/P-123/1 Butanol.  A caracterização dos filmes por MEV realizou-se após a remoção dos moldes de esferas de látex por calcinação em um forno tubular. A aparência dos filmes foi compacta para o filme de 30% V/Vo e houve uma rede de poros bem definida observada na caracterização por MEV associada à presença das esferas de látex que se auto-estruturaram pela técnica de Evaporação Controlada de Solvente (ECS).  A caracterização da superfície por MEV mostrou que esferas de látex depositam em substratos vítreos e formaram uma rede de poros que poderia ser aplicada em dispositivos funcionais como: células solares, catalisadores e baterias. Há necessidade de diminuir a concentração da dispersão para formar filmes com monocamadas homogêneas que se tornem transparentes à luz visível.
